— Yes I understand it. Thanks

Soon I will be also implementing Golang-like channels for JS... it will be crazy to see this in JS

const myChannel = new Channel("string");
spawn function() { myChannel <- "Hello!" };
console.log(<-myChannel);

— You can't tell how powerful this is... by just looking at this basic example

— But essentially, the function after spawn runs concurrently

— And the code calling spawn infact also runs concurrently

— So there can be channels of communication across several concurrent functions, without having to return/yield between them

— Why not just use Promise like semantics and fork a function call into a thread, and pass the return value back as the promise's resolv?

— Why do we need new syntax?

— Do you mean, why do we want to leave the old ways?

— It is not just new syntax

— You can easily write your own promise wrapper over it... it allows far more than this promise behavior

— It is leaving the whole event loop execution model
